Bug 1451104 - part 2 - force clang to always pick up its local GCC headers and libraries; r=glandium We want our clang bootstrap to use the GCC headers we're building with, not whatever sysroot it happens to find on the server we're building on. The -gcc-toolchain argument we specify when building clang will also be picked up by llvm-config, so we need to strip it out when building the plugin. Otherwise, we will get peculiar failures about not being able to find C++ header files. Depends on D22879 Differential Revision: https://phabricator.services.mozilla.com/D22880
